Not an expert on these but I believe it to be resin. It weighs in at 4 and a half pounds. No marks or identifications on it.

The product is a vintage statue/figure of a Bullmastiff dog, standing at 14 inches tall. The level of details in this statue is truly amazing, capturing the essence of the breed with intricate features. Fans of Bullmastiffs or collectors of animal-themed figurines would appreciate the unique and detailed design of this vintage piece.
